fix: update stopped working with banner (#22)

With the addition of `--banner` option index files no longer start with '// @create-index' This new regex looks for '// @create-index' that are either at the beginning of the file (old behavior) or if it is followed by a newline. Basically it just checks whether it exists in a file or not. Added a test for it now. # Conflicts: # src/utilities/validateTargetDirectory.js
